drizzle-orm's migrate() has a high-water-mark (HWM) bug: on a fresh DB,
migration 0000 sets the watermark to 2026-03-17. Migrations 0001, 0003,
0010, 0011 have stale 2025-era `when` timestamps and are silently
skipped. Migration 0003 (recurring_series) is the blocker — its skip
leaves `recurring_series`, `appointments.series_id`, and
`appointments.series_index` missing. A downstream migration inside
migrate()'s single Postgres transaction then fails, rolling back
everything including 0000's `staff` and `services` tables.
Replace the drizzle-orm migrate() call with `pnpm exec drizzle-kit
migrate` (hash-based). drizzle-kit applies every unhashed migration
regardless of `when` ordering, matching the K8s migrate Job exactly.
Serialize the entire db:reset chain (DROP → migrate → seed) inside one withSeedAdvisoryLock callback so a concurrent same-PRNG seeder cannot interleave and collide on invoices_pkey. Pool sized max:6 (1 reserved for the lock + work headroom) to avoid the connection-starvation deadlock the CTO caught. Verified with three end-to-end live db:reset runs against a throwaway Postgres.
